Traditional performance evaluation antennas operating with narrow band signals are not always adequately reflect the characteristics of broadband antennas, at least in view of the frequency dependence of the antenna pattern. Therefore it is important to evaluate the properties of antennas based on the spectral content of the signal, as well as taking into account the ways of its processing in the receiving equipment. Consideration of this issue is devoted to this article.</p>broadband antennabroadband signalthe radiation patternthe antenna arrayfocusing on the broadband signalsширокополосная антеннаширокополосный сигналдиаграмма направленностиантенная решеткафокусировка по широкополосному сигналу
